The final waitForContentsFullscreenState(false) occasionally times out,
probably because the KEYCODE_BACK got waylaid by some kind of dialog.
This patch adds @RetryOnFailure in the hopes of working around this.

In Public Sessions, apps and extensions are force-installed by admin policy so the user does not get a chance to review the permissions for these apps. This is not acceptable from a security standpoint, so we:
- scrub the URL available to chrome.tabs.executeScript context (through activeTab permission) down to the origin.

This change also causes the tab object passed to the [page|browser]Action.onClicked to be scrubbed for the given extension.

This case was missing test coverage and had a bug, due to it repurposing
HandleIOError, despite not using any of the existing code. Before
https://codereview.chromium.org/2771263002/, HandleIOError had an
invariant: it would either return an error code (thus continuing to
report failure), or it would reset the state machine and continue.

The new logic had a case where it returned OK without reseting the state
machine, bypassing all logic after the 421 check. Notably,
response_.ssl_info would not get filled in. Should a lower-level layer
of the stack fail with ERR_MISDIRECTED_REQUEST, the new HandleIOError
would also get confused.

Instead, inline the logic. This avoids needing a funny error code at
all. Since logging is still valuable, just add a new event type for it,
which will probably be easier to diagnose anyway. (Otherwise one needs
to know that ERR_MISDIRECTED_REQUEST never comes out of lower layers.)

Add a test that we do not retry in a loop (useful to test), and that
ssl_info is properly filled in (regression test).

Prior to this CL, SurfaceLayerImpl would always emit a SharedQuadState
for the primary and one for the fallback. This is adding unnecessary
serialization/deserialization overhead. This CL allows the two DrawQuads
to share a SharedQuadState if the device scale factor has not changed
and we are not stretching the surface. In those cases, we don't need
a different scaling transform and thus we don't need a different
SharedQuadState.

Previously, percent-height svg elements in a pure-svg doc would get
their size based on the LayoutView's logical height from the previous
layout pass.  In practice, this didn't show up much because FrameView
always does at least one extra initial layout pass to add and then
subtract scrollbars.  The extra layout pass would cause the percent
height descendants to get the right size.

Setting overlay scrollbars on the FrameView eliminates the extra
layout passes and allows the bug to manifest.

Revert of Landing Recent QUIC changes until Sat Apr 29 00:22:04 2017 +0000 (patchset #1 id:1 of https://codereview.chromium.org/2862563003/ )

Reason for revert:
Caused net_unittests to consistently time out on https://build.chromium.org/p/chromium.chromiumos/builders/Linux%20ChromiumOS%20Tests%20%28dbg%29%281%29 because of a large number of QUIC tests crashing.

on the final block, improving read locality (and avoiding a

With ARC, the order in which -dealloc is invoker is sometimes changed.
This means that some of CRWWebController delegates may end up calling
methods of CRWWebController between call to -close and -dealloc (until
the autorelease pool is cleared).

Since WebStateImpl calls CRWWebController -close just before releasing
its reference, and CRWWebController becomes unusable once -close has
been called (as -navigationManagerImpl will return nullptr), this does
not introduce an API change of CRWWebController while ensuring that
the delegate registration happens as part of WebStateImpl destruction.

While matching rules for elements, we mark elements as affected-by-* for
user action pseudo classes like hover. It means that when the element is
later hovered, we need to recalculate style to apply hover styles to
that element.

In general, we currently don't support pseudo classes after pseudo
elements, but for scrollbar pseudo elements we do:

  ::-webkit-scrollbar:hover {}

However, we do not want such rules to mark the element as affected-by-
hover. The hover style on scrollbar parts get their hover style updated
when hovered regardless of any flags, and making scrollbar pseudo
element rules affect hover updates on the actual elements causes
unnecessary style recalcs.

The outcome is: if device authorization for a renderer is taking too long
it will be interupted. Page load will continue normally, some of the audio
playback on it may not work.
